Results of sensitivity analysis in the hysterectomy cohort

Outcome misclassification rate	aOR	95% CI
10%	1.69	(1.15, 2.50)
20%	1.44	(1.02, 2.03)
30%	1.36	(0.98, 1.88)

Average adjusted odds ratios for persistent opioid use in the cancer group in the hysterectomy cohort calculated for the estimated misclassification rates, obtained by randomly reassigning 10%, 20%, and 30% of individuals without persistent opioid use to the opposite outcome. This process was repeated 100 times for each misclassification rate and the resulting odds ratios were averaged. These results show a significant increase in risk of persistent opioid use in the cancer group for up to almost 30% misclassification rate in the hysterectomy cohort.
